# Where arco Finds Your Job Matches

> Learn which job boards and platforms arco searches, how roles are filtered and de-duplicated, and what to do if a source seems to be missing postings.

arco searches across multiple platforms to find roles that match your profile. Not every job discovered becomes a match, and the same role often appears on several sources. Here is how it works.

## Where arco searches

arco queries the following platforms and boards:

* LinkedIn
* Greenhouse (used by a large share of tech companies)
* Lever
* Ashby
* Regional and local job boards, depending on your target location

## What gets filtered out

After finding postings, arco filters them by your preferences before scoring any individually:

* Your target roles and seniority
* Your locations and work-type preference
* Your salary floor (where the posting states a range)
* Anything you excluded during profile setup

## Duplicates

The same role often appears on several sources. arco de-duplicates so you see each role once.

## If a source seems to be missing roles

A few things are worth keeping in mind:

<AccordionGroup>
  <Accordion title="Not every company posts publicly">
    Some roles only exist on a company's own careers page in a format that isn't machine-readable.
  </Accordion>

  <Accordion title="Postings appear with a lag">
    A job posted an hour ago may not be indexed yet.
  </Accordion>

  <Accordion title="Your filters may be excluding it">
    Double-check your target roles, locations, and exclusions in your profile settings.
  </Accordion>
</AccordionGroup>

If you find a specific job elsewhere that arco didn't surface, you can add it yourself. See [Adding a Job Manually](/job-matches/adding-a-job-manually).
